RESET FUNCTION
System reset is performed by the followings:
“L” level is applied to the RESET pin externally,
System reset instruction (SRST) is executed,
Reset occurs by watchdog timer,
Reset occurs by built-in power-on reset (only for H version)
Reset occurs by voltage drop detection circuit (only for H version)
Then when “H” level is applied to RESET pin, software starts from
address 0 in page 0.

This symbol represents a parasitic diode.
2: Applied potential to RESET pin must be VDD or less.

Notes 1: Keep the value of supply voltage to the minimum value
or more of the recommended operating conditions.
2: It depends on the internal state at reset.

f(RING)
(1) RESET pin input
System reset is performed certainly by applying “L” level to RESET
pin for 1 machine cycle or more when the following condition is sat-
isfied;
the value of supply voltage is the minimum value or more of the rec-
ommended operating conditions.
